The benchmark corpus in the field of paraphrase detection is the Microsoft Research Paraphrase Corpus (MRPC) [1]}. It consists of 5,801 sentence pairs, where each pair is binary labeled, indicating whether it is a paraphrase or not by a human annotator. The sentences have been collected from newswire articles over two years. The corpus linked with the task of paraphrase detection is included in the GLUE benchmark [2]}, a collection of nine natural language understanding tasks.
